I learned via Yuma County's OEM that there are sirens in the towns of Joes, Kirk, Idalia, Vernon, Laird, Yuma, Wray, and Eckley Colorado. However, Google Maps will not let me explore the roads in these towns, so I cannot see what models are in these towns. If anyone has any information of sirens in these towns, I would greatly appreciate it!
The only town that I know the siren model is in the town of Eckley, which is a Federal Signal 2001.
